Article 21 of the Indian Constitution states, "No person shall be deprived of his life or personal liberty except according to procedure established by law." Over the years, the Supreme Court of India has significantly expanded the scope of Article 21 to include a wide range of rights that are considered essential for a dignified life. This includes the right to privacy, which was explicitly recognised as a fundamental right flowing from Article 21 by a nine-judge bench in the K.S. Puttaswamy vs Union of India case in 2017.
